Mohamed Quafafou, Zahi Jarir, Mohammed Erradi · 2007
The field of information extraction from the Web emerged with the growth of the Web and the multiplication of online dara sources. This paper is an analysis of information extraction methods. It presents a service oriented approach for web information extraction considering both web data management and extraction services. Then we propose an SOA bused architecture to enhance flexibility and on-the-fly modification of web extraction services. An implementation of the proposed architecture is proposed on the middleware level (J2EE servers).
